Why ThrivingPets Aluminum Hydroxide?

ThrivingPets Aluminum Hydroxide Fine Powder USP is the highest quality, most potent, and safest product on the market. Our product meets the USP standard for safety by guaranteeing safe levels of heavy metals and arsenic. Non-USP grade products may contain unsafe levels of arsenic and heavy metals.

ThrivingPets Aluminum Hydroxide Powder contains a minimum concentration of 1,200 mg per teaspoon- the highest concentration available. Non pharmaceutical grade products in the marketplace contain concentrations of 1,000 mg per teaspoon or even less. With ThrivingPets Aluminum Hydroxide Powder you administer less powder and can be confident in the purity and safety of our binder compared to the other options.


A 2001 study by Peter Markewell (BSc, BVetMed, MRCVS) for the Waltham Centre for Pet Nutrition found that "...using a phosphate- and protein-restricted diet, in combination with oral phosphorus-binding agents in those cats in which control of hyperphosphatemia [high phosphorus] and RHPTH [renal secondary hyperparathyroidism] was not achieved by diet alone, resulted in more than doubling of average survival time from the commencement of treatment."


Aluminum Hydroxide should be administered with food. This is a dose-to-effect medication, the dose should be adjusted to achieve the desired phosphorus level with the typical target of 4.0. ThrivingPets Aluminum Hydroxide Fine Powder USP contains a minimum of 1,200 mg of Aluminum Hydroxide per teaspoon. There are approximately 100 teaspoons of powder in the 200 gram jar.

For wet food: Place the food in the serving bowl, add the ThrivingPets Aluminum Hydroxide Powder to the food, add water equal to 3 times the amount of the powder, mix thoroughly, and let the food sit for at least 15 minutes before serving. The water and letting the food sit are to help the powder hydrate and the particles to break down so your pet can't detect the powder in the food.

For dry food: Place the daily amount of food and ThrivingPets Aluminum Hydroxide Powder into a zip-lock bag and shake well. Let sit for at least 4 hours to allow the powder to absorb into the oil in the food.

Drug Interactions (Source:

Potassium Citrate 

As Prescribers' Digital Reference mentions, products containing citrate may increase the absorption of aluminium, which could increase the risk of aluminium toxicity (though apparently these findings have not been replicated in cats). The most commonly used citrate-containing products in CKD cats are potassium citrate (perhaps to treat metabolic acidosis), and many therapeutic kidney diets.

If you are using potassium citrate, give this at least two hours apart from aluminium-based binders.

Other Interactions

  • Plumb's also recommends separating aluminium hydroxide from corticosteroids.

  • Aluminium hydroxide should ideally be given separately from oral iron supplements because the aluminium hydroxide may reduce the absorption of the iron.

  • Plumb's Veterinary Drug Handbook also advises giving aluminium hydroxide two hours apart from famotidine (Pepcid AC), which is used to treat excess stomach acid, because it may interfere with the absorption of the treatment, which would make it less effective. However, RX Med states that "concomitant use of aluminum hydroxide/magnesium hydroxide at commonly used doses, does not influence the pharmacodynamics or bioavailability of Pepcid AC." I would try to err on the side of caution and still separate famotidine from phosphorus binders and ACE inhibitors if you can, but if this is difficult for you, e.g. because of work commitments, just do the best you can.

  • Aluminium hydroxide binders should be given two hours apart from ACE inhibitors, because the binder may reduce the bioavailability of the ACE inhibitors. Drugs has more information about this.

  • Pennstate Hershey mentions that vitamin C may interact adversely with products containing aluminium, such as phosphorus binders. Cats do not need vitamin C supplements anyway, because their bodies can manufacture all the Vitamin C they need.

Needles and med

Plus, the medication seems to be working beautiful

Great Product

I've been giving this to my senior CKD kitty for well over a year now. I would recommend it to anyone who has a cat with kidney disease.

ThrivingPets Aluminum Hydroxide Fine Powder USP 200 Gram Jar

There was no measuring scoop.

Waiting on my cats labs to see if this helping. Scoop would have been nice.

Thank you for providing feedback on the ThrivingPets Aluminum Hydroxide Powder. We choose not to include a scoop because some clients dose 1/8 teaspoon, others administer a teaspoon, and others dose by the tablespoon. Most of our clients have measuring spoons and select the correct measuring spoon to administer the dose needed for their pet.

Hard to dissolve

I spoke with a representative of Thrivingpets about the difficulty of dissolving the aluminum hydroxide and he suggested putting kibble with the powder in a bag and it worked perfectly
Thanks for the great advice
